]]>We have had a lot of celebrities tweeting their UFO encounters lately, but now NASA is getting in on the UFO tweet action. Chris Hadfield, Canadian astronaut and the commander of Expedition 35 on the International Space Station, has tweeted a few pictures today of what he calls a huge piece of debris.

The “debris” is clearly a saucer shaped object. He later tweeted another picture and said he was going to grab it with the Canadarm2. His next tweet was more distressing. It exclaimed, “The object appears to be coming closer to the Station. I think it might be trying to board us!”

However, unsurprisingly, Hadfield has finally shown his hand. In his last tweet on the UFO affair, Hadfield wrote: “I don’t know what it is or what it wants, but it keeps repeating “Sloof Lirpa” over and over. Alert the press.”

This time the attached picture was a cartoony little alien in the ISS. Was this whole thing an elaborate hoax? Given that Sloof Lirpa is April Fools backwards, I think that is a safe bet.

]]>This week Russell Crowe tweeted possible UFO pictures taken above Sydney’s Royal Botanic Gardens in Australia. The pictures were put together in a video uploaded to YouTube on Tuesday, and were originally part of some time lapse photography Crowe and a friend set up to capture fruit bats.

Crowe’s representative in Australia told the Australian news website, news.com.au, that the photos were actually taken four years ago, and he is unsure why Crowe decided to tweet them this week. News.com.au suggests in their story that it might have been to spark some publicity for the release of Crowe’s latest film, Broken City. Earlier in the day Crowe had tweeted frustration with the lack of publicity for the film.

Many of the people commenting on the YouTube video have suggested that the strange lights could be due to lens flares. Some of them noted car tail lights and possible boat lights in the area. However, Crowe argues against the flare theory because he says the lights are moving and the camera was not behind glass. Check out the video below and decide for yourselves.
